PRODUCT BRIEF
155 Mbps and 622 Mbps Clock and Data Recovery Units
Vitesse’s high-speed clock and data recovery devices deliver industry-leading jitter performance
Vitesse’s newly improved multirate clock and data recovery (CDR) devices
provide exceptional input sensitivity, jitter tolerance, and jitter transfer
performance.
The VSC8115-05 and VSC8115-06 devices derive high-speed timing
signals for SONET/SDH-based equipment. The devices are designed to
operate with SONET framer or ASIC devices to provide a low-power,
high-speed clock and data recovery interface for optical networks.
The devices achieve impressive jitter tolerance of 0.45 UI, jitter input
sensitivity of 150 mV, and jitter transfer compliance in JMODE. Meets all
Telcordia, ANSI, ITU-T, and SONET jitter requirements.
The VSC8115-05 and VSC8115-06 feature signal and lock-detect status
outputs, automatic lock-to-reference, and PLL bypass for on-board
debugging. High-speed outputs are configurable for either LVPECL or
LVDS.
Available in a 20-pin TSSOP package for flexible implementation and
simplified layout, the VSC8115-05 device supports commercial temperature
ranges, and the VSC8115-06 supports industrial temperature ranges. Both
devices come in tape and reel form and are available in lead(Pb)-free
versions.
